Antony Chesney has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A tethered ligand comprising the reaction product of an organofunctional silica and a ligand containing a functional group capable of reaction with said organofunctional silica, wherein the organofunctional silica is prepared from an alkyl silicate and an organofunctional silane is described. A supported catalyst is also described comprising additionally a source of catalytically-active metal. Methods for preparing the tethered ligand and supported catalyst are provided and uses of the supported catalyst for performing asymmetric reactions are claimed. The catalysts are readily separable from the reaction mixtures and may be re-used if desired.
